  • Patent number: 12665102
    Abstract: In an exemplary embodiment of the present invention: A series of U-shaped nickel-iron components are plated onto a rough or roughened semiconductor package or printed circuit board material. The horizontal base of the U-shaped component has a surface roughness of the semiconductor package material. The vertical surfaces of the U-shape have a surface roughness derived from the dry film. The large smooth vertical surface allows the U-shaped nickel-iron components to have a low average roughness. The lowered average roughness reduces the path length the U-shaped nickel-iron components provide for magnetic flux while the roughness of the horizontal portion of the U-shape allows for increased mechanical bonding to occur.
